Public Overridable Function TrySignHash (hash As ReadOnlySpan(Of Byte), destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean

参数

hash: ReadOnlySpan<Byte>

正在签名的数据的哈希值。

destination: Span<Byte>

要接收签名的缓冲区。

bytesWritten: Int32

此方法返回时，包含写入 destination到的字节总数。此参数被视为未初始化。

Boolean

false 如果 destination 没有足够的时间接收签名，则为
